DETAILED DESCRIPTION OF EMBODIMENTS

The following part will illustrate exemplary embodiments of the present disclosure with reference to the drawings, including various details of the embodiments of the present disclosure for a better understanding. The embodiments should be regarded only as exemplary ones. Therefore, those skilled in the art should appreciate that various changes or modifications can be made with respect to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for clarity and conciseness, the descriptions of the known functions and structures are omitted in the descriptions below.

Apparently, the embodiments to be described are merely a part rather than all of the embodiments of the present disclosure. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

It should be noted that a terminal device in the embodiments of the present disclosure may include, but is not limited to, a mobile phone, a personal digital assistant (PDA), a wireless handheld device, a tablet computer, and other smart devices; a display device may include, but not limited to, a personal computer, a television, and other devices with a display function.

In addition, the term “and/or” only describes an association relationship between associated objects, and indicates that three relationships may exist. For example, A and/or B may indicate three cases: only A exists; both A and B exist; and only B exists. In addition, in this specification, the symbol “/” generally indicates that associated objects have a relationship of “or”.

Machine translation (MT) may be defined as: input: a source language sentence containing n words X = (x₁, x₂, ... ... , x_(n)); and output: a translation result Y = (y₁, y₂, ....... Y_(m)) corresponding to X, where an ith word translated on a target side may be represented as y_(i), and may also be referred to as an ith token in a neural network model.

In iterative non-autoregressive machine translation (NAT) models, a single translation model is used for inference, and multiple translation models cannot be used for fusion. Translation quality of the iterative NAT model may be improved using the fusion of the multiple translation models.

FIG. 1A is a translation principle diagram of an autoregressive model according to the present disclosure; and FIG. 1B is a translation principle diagram of a non-autoregressive model according to the present disclosure. Taking original text “It is amazing” and a target translation result

(Zhen shi tai shen qi le) ” as an example, as shown in FIG. 1A, the autoregressive model is required to perform an m-step decoding operation to generate a translation result with a length m, which has an obvious disadvantage of a low speed. To solve the m-step decoding problem caused by dependency on the target side, the non-autoregressive translation model shown in FIG. 1B may be adopted. As shown in FIG. 1B, translation may be achieved by a two-step decoding operation. In the first step, X is encoded, a length is predicted, and then, the input is changed to [M] with a corresponding length, i.e., [Mask]. These [M]s are predicted into corresponding target words using a decoder for parallel decoding, and a complete sentence translation result is generated through multiple iterations; several words with high probabilities are selected and fixed in each iteration and used for generating other words in subsequent iterations. For example, in the first step, a predicted result is the result of the following table 1:

TABLE 1 0.6 0.7 0.6 0.9 0.7 0.8

(zhe)

(ke)

(zhen)

(shen)

(qi)

(le)

If the model sets a number of the words determined each time as a number of tokens of ⅓ of the length of the target translation result, the number is 6/3=2 in the case of above Table 1. Then,

and

may be used as translation content determined in the first step. “[M] [M]

is input during the second decoding step of the decoder. FIG. 1C is an ideal schematic translation diagram of the non-autoregressive model according to the present disclosure; for example,

and

may be produced in the first step,

and

may be iteratively produced in the second step, and all remaining words may be iteratively produced in a third step. FIG. 1D is an actual schematic translation diagram of the non-autoregressive model according to the present disclosure; FIG. 1D shows a problem which is prone to occur in a real scenario. Since an incorrect inference result

is generated and fixed in the first step, the following translation results are all wrong.

However, in practical applications, the following two translation results are applicable to “It is amazing”:

-   “     (Zhen shi tai shen qi le) ”; and -   “     (Tai bu ke si yi le) ”.

The model does not consider generation of a dependency relationship between tokens in a NAT generation mode, such that the model may produce the following results mixing the two translations in Table 2 during the first iteration:

TABLE 2 0.7 0.9 0.8 0.9 0.6 0.8

(tai)

(bu)

(ke)

(shen)

(yi)

(le)

If

and

are determined in this step, an error of a final translation result will be caused directly. As shown in FIG. 1D, light-colored words represent the tokens with output probabilities not ranking among the top ⅓ of the results output by the decoder, and dark-colored words represent the tokens inferred to be incorrect and correct in determined tokens.

FIG. 2 is a schematic diagram according to a first embodiment of the present disclosure; as shown in FIG. 2 ,this embodiment provides a translation method, which may be applied to a translation apparatus, and specifically includes the following steps:

S201: acquiring an intermediate translation result generated by each of multiple pre-trained translation models for a to-be-translated specified sentence in a same iteration of a translation process, so as to obtain multiple intermediate translation results.

The translation method according to this embodiment is applied to a translation apparatus incorporating multiple translation models. For example, in a process of translating the specified sentence by the multiple translation models in this embodiment, multiple iterations are required, and one candidate translation result is obtained in each iteration. After each intermediate iteration, one intermediate translation result is obtained.

Since the translation of the specified sentence by the multiple translation models in this embodiment is required to be completed through the multiple iterations, optionally, the multiple translation models in this embodiment may be non-autoregressive translation models. For an implementation principle of the non-autoregressive translation model, reference may be made to the related descriptions of FIGS. 1B and 1C. Optionally, the multiple translation models may also be other models required to obtain translation results through multiple iterations, which is not limited herein.

The multiple intermediate translation results obtained in the step are generated by different translation models in the same iteration. For example, the intermediate translation result generated by each of the multiple translation models in the first iteration is selected to obtain the multiple intermediate translation results. Then, each translation model continues to perform a second iteration to generate a further intermediate translation result based on the intermediate translation result generated in the first iteration, and with the method according to this embodiment, the intermediate translation result generated by each of the multiple translation models in the second iteration may be selected to obtain the multiple intermediate translation results; by analogy, an intermediate translation result generated by each of the multiple translation models in any same iteration of the translation process may be selected to obtain the multiple intermediate translation results.

S202: acquiring a co-occurrence word based on the multiple intermediate translation results.

Each intermediate translation result in this embodiment includes multiple words. The co-occurrence word in this embodiment is a word co-occuring in at least two of the multiple intermediate translation results.

S203: acquiring a target translation result of the specified sentence based on the co-occurrence word.

The multiple intermediate translation results are generated by different translation models, if the co-occurrence word appears in the intermediate translation results generated by different translation models, the result translated by the translation model has a greater probability of being the target translation result, and if the co-occurrence word does not appear in the translation result, the result translated by the corresponding translation model has a smaller probability of being the target translation result. Based on this concept, in this embodiment, the target translation result of the specified sentence may be acquired based on the co-occurrence word, thus improving the accuracy of acquiring the target translation result.

In the translation method according to this embodiment, with the above technical solution, acquirement of the target translation result of the specified sentence is realized based on the co-occurrence word, which may effectively avoid confusion of the target translation result by a non-co-occurrence word, thus effectively improving the translation accuracy.

FIG. 3 is a schematic diagram according to a second embodiment of the present disclosure; as shown in FIG. 3 , this embodiment provides a translation method, and the technical solution of the present disclosure is further introduced in more detail based on the technical solution of the above-mentioned embodiment shown in FIG. 2 . As shown in FIG. 3 , the translation method may include the following steps:

S301: acquiring an intermediate translation result generated by each of multiple pre-trained translation models for a to-be-translated specified sentence in a same iteration of a translation process, so as to obtain multiple intermediate translation results.

S302: acquiring a co-occurrence word based on the multiple intermediate translation results.

S303: acquiring, based on the co-occurrence word, candidate translation results obtained from the translation of the specified sentence by at least two corresponding translation models, so as to obtain at least two candidate translation results.

The co-occurrence word appears in at least two intermediate translation results, each intermediate translation result corresponds to one translation model, at least two intermediate translation results correspond to at least two translation models, and the at least two translation models necessarily correspond to at least two candidate translation results of the specified sentence, thereby obtaining the at least two candidate translation results.

In this embodiment, the at least two candidate translation results may be acquired based on the co-occurrence word in any iteration. The at least two candidate translation results may also be acquired based on the co-occurrence word in each iteration.

S304: acquiring a target translation result of the specified sentence from the at least two candidate translation results.

A probability corresponding to the candidate translation result will be output while each translation model finally outputs the candidate translation result. In this embodiment, the final target translation result of the specified sentence may be determined using the probability of each candidate translation result.

For example, according to the probability of each candidate translation result, the candidate translation result with the highest probability may be acquired from the at least two candidate translation results as the target translation result of the specified sentence, which may ensure that the acquired target translation result is a most effective and accurate translation result.

Optionally, the target translation result of the specified sentence may also be acquired from the at least two candidate translation results with other methods; for example, a scoring model may be used to score based on each candidate translation result and the specified sentence to acquire a score of the candidate translation result, so as to identify the accuracy of the translation of the candidate translation result of the specified sentence. Further, according to the scores of the at least two candidate translation results, the candidate translation result with the highest score may be acquired as the target translation result of the specified sentence. In addition, the target translation result of the specified sentence may be acquired from the at least two candidate translation results with other methods, which is not limited herein.

The steps S303-S304 in this embodiment are an implementation of the step S203 in the above-mentioned embodiment shown in FIG. 2 .

In the translation method according to this embodiment, with the above technical solution, based on the co-occurrence word, the candidate translation results obtained from the translation of the specified sentence by the at least two corresponding translation models are acquired to obtain the at least two candidate translation results; and then, the target translation result of the specified sentence is acquired from the at least two candidate translation results, such that the target translation result may be acquired based on the co-occurrence word, confusion of the target translation result by a non-co-occurrence word is effectively avoided, and the translation accuracy may be guaranteed effectively.

FIG. 4 is a schematic diagram according to a third embodiment of the present disclosure; as shown in FIG. 4 , this embodiment provides a translation method, and the technical solution of the present disclosure is further introduced in more detail based on the technical solution of the above-mentioned embodiment shown in FIG. 3 . As shown in FIG. 4 , the translation method may include the following steps:

S401: acquiring an intermediate translation result generated by each of multiple pre-trained translation models for a to-be-translated specified sentence in a first iteration of a translation process, so as to obtain multiple intermediate translation results of the first iteration.

S402: acquiring a co-occurrence word of the first iteration based on the multiple intermediate translation results of the first iteration.

S403: detecting, based on the co-occurrence word of the first iteration, whether the iteration at which each of the at least two corresponding translation models generates the intermediate translation result of the first iteration is the last iteration; if the iteration is the last iteration, executing step S404; if the iteration is no the last iteration, executing step S405.

Specifically, it may be detected whether the intermediate translation result obtained in this iteration includes other untranslated token(s) in addition to the co-occurrence word, if other untranslated token(s) is (are) included, the iteration is not the last iteration, and iterative translation is required to continue, and if no other untranslated token is included, the iterative translation is not required to continue, and this iteration is the last iteration.

S404: taking the intermediate translation result generated by the corresponding translation model in the first iteration as a candidate translation result obtained from the translation of the specified sentence by the translation model; then executing step 409.

S405:controlling, based on the intermediate translation result of each of the at least two translation models in the previous iteration, the corresponding translation model to continuously perform current iterative translation, so as to obtain at least two intermediate translation results of the current iteration; then executing step 406.

S406: acquiring a co-occurrence word of the current iteration based on the multiple intermediate translation results of the current iteration; then executing step 407.

S407: detecting, based on the co-occurrence word of the current iteration, whether the iteration at which each of the at least two corresponding translation models generates the intermediate translation result of the current iteration is the last iteration; if the current iteration is the last iteration, executing step S408; if the current iteration is not the last iteration, executing step S405.

S408: taking the intermediate translation result generated by the corresponding translation model in the current iteration as a candidate translation result obtained from the translation of the specified sentence by the translation model; then executing step 409.

Based on the above description, in this embodiment, in each iteration, the corresponding translation model is controlled to continuously perform a next iteration based on the co-occurrence word, and the process is repeated until the corresponding candidate translation result is acquired.

In this embodiment, for example, the co-occurrence word is screened in each iteration, and if there is an intermediate translation result without the co-occurrence word in any iteration, the translation result of the specified sentence by the corresponding translation model is not used as the target translation result.

In this embodiment, a number of words included in the intermediate translation result generated in each iteration, i.e., a number of tokens, may account for 1/N of the total length, N being any positive integer greater than 1. Alternatively, a number of tokens included in the intermediate result generated in each iteration may be set to any preset positive integer. Alternatively, a probability of a token included in the intermediate result generated in each iteration may be set to be greater than a preset probability threshold; that is, a number of the tokens is not set in this case. In practical applications, the setting may be performed according to requirements, and is not limited herein.

S409: acquiring, according to the probability of each candidate translation result, the candidate translation result with the highest probability from the at least two candidate translation results as the target translation result of the specified sentence.

FIG. 5 is an example diagram of one translation method according to the present disclosure; and as shown in FIG. 5 , a translation apparatus incorporating four translation models is taken as an example, and original text “It is amazing” and a target translation result “

(Zhen shi tai shen qi le) ” are taken as an example. As shown in FIG. 5 , in a first iteration, an intermediate translation result of translation model 1 is “

(shen) ,

(le) ”; an intermediate translation result of translation model 2 is “

(shen) ,

(le) ”; an intermediate translation result of translation model 3 is “

(shen) ,

(le) ”; and an intermediate translation result of translation model 4 is any word of “

(bu) ,

(ke) ,

(si) ,

(yi) ”. In this way, in the intermediate translation results of the first iteration, a co-occurrence word exists in the intermediate translation results of the translation model 1, the translation model 2 and the translation model 3, and at this point, the intermediate translation result of the translation model 4 is discarded. Only the intermediate translation results of the translation model 1, the translation model 2 and the translation model 3 are considered.

Next, in a second iteration, an intermediate translation result determined by each translation model includes both a word newly generated in this step and the word determined in the previous iteration. If the intermediate translation results of the translation model 1, the translation model 2 and the translation model 3 in the second iteration are “

(tai) ,

(shen ) ,

(qi) ,

(le) ”, and the iteration of the translation model 3 in the second iteration is the last iteration, a corresponding candidate translation result

(Tai shen qi le) ” is obtained. The translation model 1 and the translation model 2 continue to perform a next iteration, and finally, candidate translation results “

(Zhen shi tai shen qi le) ” and “

(Zhe tai shen qi le a) ” are obtained. Finally, according to a probability of each candidate translation result, the candidate translation result with the highest probability may be taken as the target translation result. For example, the translation result of the translation model 1 has the highest probability in this embodiment, and may be used as the target translation result.

In the translation method according to this embodiment, with the above technical solution, the translation result corresponding to the non-co-occurrence word may be discarded, and only the translation result corresponding to the co-occurrence word is taken as the candidate translation result, such that the target translation result is acquired from the at least two candidate translation results, confusion of the target translation result by the non-co-occurrence word is effectively avoided, and the translation accuracy is improved effectively.
